MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 769,285, dated September 6, 1904. Application filed July 80, 1903. Renewed July 25, 1904 Serial No. 218,111. (No model.)

To (LZZ whom, trim/(by concern.-

Be it known that I, JosErH ZANDALAZINI, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Musical Instruments; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to musical instruments, and more particularly to improvements in attachments for self-playing organs or pianos by means of which drums, bells, or other musical devices may be played.

The object of the invention is to provide an attachment of this character which may be readily applied to any of the self-playing musical instruments and which is adapted to be operated from the mechanism of such instrument.

Further objects are to improve and simplify the construction of this class of devices, to provide a strong, durable, and attractive instrument, and to render the same more eflicient in operation. v

I/Vith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claim.

In the drawings, Figure 1 is a front elevation of my improved attachment, showing the same mounted upon the top of a self-playing piano or organ. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view with the ornamental top, the drum, and cover of the box removed in order to show the interior mechanism. Fig. 41. is a vertical transverse sectional view through attachment and the upper portion of a self-playing organ or piano. The section is taken on the line 41 at of Fig. 3 and shows the connection of the gearing or operating mechanism between the attachment and the organ or piano. Fig. 5 is a vertical transverse sectional view through the attachment, taken on the line 5 5 of Fig. 3 and showingthedrum-operatingmechanism. Fig. 6 is a similar sectional View taken on the line 6 6 of Fig. 3 and showing the bell-operating mechanism. Fig. 7 is a vertical longitudinal sectional view taken on the line 7 7 of Fig. 3. Fig. 8'is a detail sectional view taken on the line 8 8 of Fig. 1. Fig. 9 is a' detail sectional View taken on the line 9 9 of Fig. 8. Fig. 10 is a detail sectional view taken on the line 10 10 of Fig. 3. Fig. 11 is a detail sectional View taken on the line 11 11 of Fig. 6.

Referring to the drawings more particularly, the numeral 1 denotes the upper portion of the casing or frame of a self-playing organ or piano, upon the top of which my improved attachment 2 is secured. The frame or casing of the attachment comprises the rectangular box 3 and the ornamental top frame 1, which is detachably secured upon the cover 5 of said box by providing the same with the dowel-pins 6 and the pivoted hooks or catches 7, which engage eyes 8 upon said cover. The cover 5 may be provided with the hinged portions or doors 9, which permit access to the mechanism in the box 3.- The box or casing 3 may be detachably secured upon the top of the organ or piano in any desired manner; but I preferably provide the top or cover of the casing 1 with an inlaid plate 10, which is engaged by the catch or hook 11, secured to the bottom of the box 3, as shown in Fig. 7 of the drawings. I also secure to the top of the casing 1 the apertured ear or lug 12, which projects through an opening in the bottom of the box 3 and which is engaged by a pivoted hook'or catch 13 upon the upper side of the bottom of said box. 7

The front side of the box 3 is provided with suitable openings, in which the drum 14 and the two bells 15 are mounted. The drum 14, which may be of any desired form or construction, is held in the opening in the front of the box 3 and the top frame 1 by means of the brackets 16, the hooked ends of which engage the back or inner rim of the drum, as seen in Fig. 5. The bells 15, as shown in Fig. 6, are secured upon the ends of the curved brackets 17, which are fastened to the bottom of the box upon the inside thereof.

Extending longitudinally through the box 3 is a shaft 18, upon which the cylinder 19 is secured. This cylinder is provided with pins be easily removed.

played by the organ.

or projections 20, by means of which the drumoperatmg and bell-operating mechanisms are operated, as hereinafter described. There are nular rows, the number of rows in each group corresponding to the number of tunes which the piano or organ is capable of playing and each row being adapted to operate one of the instruments or devices during a particular tune or air.

In order to bring any desired row of pins into position for operating the proper drum or bell-actuating mechanism, the shaft 18 is slidably mounted in the box in order to move the cylinder longitudinally. One end of said shaft projects through a central aperture in a door 21, which closes a circular opening 21 in one end of the box 3. This door is removably held in said opening by providing the lower fixed catch 22 and the pivoted upper catch or latch 23. The opening 21 is provided to permit the cylinder and its shaft to The opposite end of the shaft 18 projects through an opening in the other end of the box and is provided with a series of annular grooves 24, which correspond in number to the number of the rows of pins 20 in each group or to the number of tunes These grooves are separated by the same intervals or spaces as the rows of pins are. It will be seen by this arrangement that when the shaft is moved longitudinally, so that, for instance, the first groove is at a desired point in the opening in the end of the box, the first row of each group of pins will be in the proper position to actuate the desired mechanism.

In order to hold the shaft at any desired position, the pivoted lever 25 is provided upon the outside of the end of the box, which lever is adapted to engage one of the grooves 24, as seen in Figs. 2 and 7 of the drawings. The lever is provided with a handle and swings between suitable guides 26, which also serve to hold the spring 28 upon said lever to prevent casual disengagement of the latter from the grooves 24.

WVithin the box 3, above and to one side of the center of the cylinder, is a movable bar 30, which carries a series of pivoted dogs or levers 31, which are operated by the pins 20 in order to actuate the drum and bell operating mechanisms. Upon each end of this bar is secured an arm 32, which is pivoted at 33 to permit said movable bar to have a swinging movement. The arm 32 at one end is provided with an extension 34, as seen in Figs. 3 and 4, which extension rests upon a cam 35, secured upon the inner end of a shaft 36, which projects through the end of the box. The

outer end of this shaft is provided with an cured.

operating-handle 37, by means of which the movable bar may be elevated or swung up to throw the studs or projections 38 upon the dogs 31 out of the path of the pins 20, and thereby throw the attachment out of operation. Suitable springs 40, secured in brackets 41 upon the back of the box, have their ends or arms 42 seated in recesses 43 in the top of the bar 30 and are adapted to hold said bar and the dogs down in their operative position upon the cylinder. The downward movement of this movable bar is limited by the stop or bracket 44, which is secured upon the inside of the end of the box.

The dogs 31, which are operated by the pins 20 on the cylinder, are pivoted in slots or openings 45 in the under side of the movable bar and are controlled in their movement by the regulating-plate 46. This plate, as clearly shown in Fig. 10, is adjustably secured upon the front side of the shifting bar 30 by providing the screws 47, which pass through elongated slots 48 in the plate 46. By adjusting this plate vertically it will be seen that the movement of the dogs may be limited.

The forward ends of the two end dogs 31, which operate the bells, are connected by the links 50 to the inner ends of the levers, which form bell strikers or hammers 51. These levers 51 are pivoted in the brackets 52 and have their forward ends projecting through vertical slots in the front wall of the box and provided with the heads 53, which are adapted to strike the bells. The coil-springs 54, which have their ends secured to the levers 51 and the bottom of the box, are adapted to pull said hammers down to strike the bell after they have been elevated by the dogs 31 and links 50. The forward ends of the hammer levers 51 are adapted to be supported in order to hold the heads 53 off the bells by providing the springs 55, which extend trans versely across the openings in the front wall and which are secured in the blocks 56. These springs are of greater strength than the springs 54; but the impact of the hammer as it descends under the action of the spring 54 will be sufficient to overcome the resistance of the spring 55 and will hence be permitted to strike the bell.

The drum sticks or heaters for operating the drum consists of the spring-arms 60, upon the upper ends of which the heads are se- The lower portions of these arms or levers 60 are curved or bent at right angles and project through openings 61 in the front wall of the box. This portion 62 of the levers is provided with a series of apertures, by means of which said lever may be adjustably pivoted between the ears or lugs 63 of the bracket 64, which is fastened upon the bottom of the box. The free end 65 of the portion 62 of the lever is offset and provided with a series of apertures or openings. The links 66 IIO have their upper ends adjustably connected to said ends of the levers 60 and their lowerand impact caused by the operation of the arms or heaters 60. It will be seen that the movement of the dogs 31, caused by the pin 38 riding over the pins 20, will operate the drum sticks or heaters 60 by means of the levers just described. In order to cause the beater arms or levers 60 to rebound and strike the drum-head after they have been moved away from the same by the dogs 31, I provide the springs 71, the ends 72 of which engage the ends 65 of said levers.

In order to operate the cylinder 19, I provide one end of the same with a gear 73, which is in mesh with a worm 74 upon a vertical,

shaft 75, having its upper end journaled in a bearing-bracket 76, secured upon the inside of one end of the box. The lower end of this shaft is journaled in a plate 77, secured upon the bottom of the box, and has fixed to it the gear 78. In order to drive this gear 78 and shaft to operate the cylinder, I provide suitable gearing to connect them to the driveshaft 79 in the piano or organ. This shaft, as clearly shown in Fig. 4, is of the ordinary construction, being journaled in a bearing 80 and in the back wall of the casing 1, through which it projects in order to receive the operating crank-handle 81. Said shaft, as shown, is provided with the worm 83 for operating the organ-cylinder or other mechanism and with the two cranks, to which the pitman-rods 84 are connected, which rods operate the pumps or bellows. Upon this d riveshaft 7 9 I secure a bevel-gear 85, which is adapted to mesh with a similar gear 86, secured upon the lower reduced end of a vertical shaft 87. as seen in Figs. a and 9, is journaled in a bearing-bracket 88, secured upon the inside of the casing 1, and projects through the top of the same, the bottom of the box 3, the plate 77, and a gear adjusting or regulating plate 89. The upper reduced end of this shaft 87 has secured to it the gear 90, which is adapted to be connected to the gear 78 by the gear 91. The gear 91 is journaled upon a fixed stud or post 92, projecting vertically from the adjusting-plate 89. The plate 89 is practically pivoted upon thev shaft 87 beneath the gear 90 and is provided with the fingerpiece or handle 93, by means of which said plate may be swung to move the gear 91 into and out of mesh with gears 78 and 90 or to adjust said gears to permit them to work more or less freely. To hold the plate 89 and its gear 91 This shaft,

in an adjusted position, I provide the same with the arc-shaped slot 9 1, which engages. a screw-threaded post or bolt 95, projecting from theplate 89. A clamping wing-nut 96 and washer upon said screw securely binds the plate 89 down upon the plate 77.

The operation of the invention is as follows: hen the parts areproperly assembled, as shown in the drawings, the rotation of the crank-handle 81 of the piano or organ will set the mechanisms in both the organ and the attachment in operation and cause a tune to be played. The motion of the drive-shaft 79 will be communicated to the cylinder 19 .of the attachment through the gears 85 and 86, the shaft 87, the gears 90, 91, and 78, the shaft 7 5, the worm 74, and the gear 73 upon said cylinder. In the rotation of the cylinder the pins 20 upon the same will contact with the pins or projections 38 upon the dogs 31, and thereby operate said dogs, as will be readily understood. The movement of some of the dogs will be imparted to the bell-operating mechanisms, and thereby ring the bells, while the movement of the remaining dogs will actuate the drui'n-operating mechanism to beat the drum, as previously explained. By means of the various adjustments previously described the operation of these mechanisms may be regulated in a manner which will be readily understood. When it is desired to play a different tune, the movable bar 30 is first elevated, by means of the hand-lever 37, to move the dogs 31 and their pins 38 out of the path of the pins 20 on the cylinder. The cylinder is then shifted to bring the proper rows of pins 20 beneath the pins 38 by first disengaging the hand-lever 25 from the grooves 24 and then moving the shaft longitudinally. After the cylinder has been adjusted the movable bar is then lowered.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

While I have illustrated in the drawings but four dogs 31 for actuating the drum and bells, it will be understood that, if desired, any number of these dogs may be provided for actuating any number of drums, bells, or other musical instruments or devices.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
